Abstract
A surface-morphology change has been observed for an aluminide coating on t
he Go-base superalloy DZ40M during oxidation at 1100 degrees C in air. The
oxide formed on the coating remained an even greyish-white color during the
stable oxidation stage, whereas, dark-colored corrosion nodules were obser
ved when oxidation of the coating accelerated. The number of nodules increa
sed with time, along with growth of the nodules, eventually covering the en
tire surface which signified failure.
